Subject: [RFC PATCH 1/6] Documentation: arm: ti: Add bindings for AM654 SoC
Date: Tue, 5 Jun 2018 01:01:20 -0500	[thread overview]
Message-ID: <20180605060125.9518-2-nm@ti.com> (raw)
In-Reply-To: <20180605060125.9518-1-nm@ti.com>

The AM654 SoC is a lead device of the K3 Multicore SoC architecture
platform, targeted for broad market and industrial control with aim to
meet the complex processing needs of modern embedded products.

Some highlights of this SoC are:
* Quad ARMv8 A53 cores split over two clusters
* GICv3 compliant GIC500
* Configurable L3 Cache and IO-coherent architecture
* Dual lock-step capable R5F uC for safety-critical applications
* High data throughput capable distributed DMA architecture under NAVSS
* Three Gigabit Industrial Communication Subsystems (ICSSG), each with dual
  PRUs and dual RTUs
* Hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
* Centralized System Controller for Security, Power, and Resource
  management.
* Dual ADCSS, eQEP/eCAP, eHRPWM, dual CAN-FD
* Flash subystem with OSPI and Hyperbus interfaces
* Multimedia capability with CAL, DSS7-UL, SGX544, McASP
* Peripheral connectivity including USB3, PCIE, MMC/SD, GPMC, I2C, SPI,
  GPIO

See AM65x Technical Reference Manual (SPRUID7, April 2018)

+Texas Instruments K3 Multicore SoC architecture device tree bindings
+--------------------------------------------------------------------
+
+Boards based on K3 Multicore SoC architecture shall have the following property:
+- compatible: Every hardware block introduced in K3 Multicore SoC
+  architecture shall be of the form:
+  "ti,XXX-YYY", where:
+     'XXX' represents the specific SoC part for which the support is added.
+     'YYY' represents the corresponding peripheral in SoC being supported.
+
+  NOTE: Generic devices such as GIC or legacy devices shall use the specified
+  compatible for those devices.
+
+  Example:
+    compatible = "ti,am654-i2c";
+
+SoCs
+-------------------------------------------
+
+Each device tree root node must specify which exact SoC in K3 Multicore SoC
+architecture it uses, using one of the following compatible values:
+
+- AM654
+  compatible = "ti,am654";
+
+Boards
+-------------------------------------------
+
+In addition, each device tree root node must specify which one or more
+of the following board-specific compatible values:
+
+- AM654 EVM
+  compatible = "ti,am654-evm", "ti,am654";
